Physical properties
Hardness: 6.5-7 (Mohs scale), Color: tan, brown, black, and cream in landscape-like patterns, Luster: vitreous to dull, Crystal Structure: Trigonal (microcrystalline/cryptocrystalline), Cleavage: None, Specific Gravity: 2.58-2.91
Formation & geological history
Formed through the flow of mineral-rich water or volcanic ash through mud and cracks. The distinctive 'pictures' are created by high iron content and other mineral oxides that petrify over millions of years, often in volcanic or sedimentary environments.
Uses & applications
Primarily used in jewelry (pendants, beads), cabochons, metaphysical practices, and as decorative ornamental stone.
Geological facts
Picture Jasper is often called a 'hidden message' stone; many believe its patterns represent scenes from the earth's past or landscape 'maps' of ancient civilizations.
Field identification & locations
Identified by its opaque, porcelain-like texture and complex, dendritic or swirling patterns that resemble landscapes. Commonly found in Oregon, USA (the Biggs and Deschutes areas are famous for high-quality specimens).
